CAR-PLATFORM GATE.

Specicaton of Letters Patent.

T0 all wtont it waa/y concern:

Be it known that I, HUBERT WITTE, a citizen of the United States,residing in the city of St. Louis, in the .State of Missouri, haveinvented certain new and useful Improvements in Oar-Platform Gates, ofwhich the following is a full, clear, and eXact description, referencebeing had to the accompanying drawings, forming part of thisspeciiication.

My invention relates to a gate for the platforms of railway-cars,especially those used upon street-railways; andthe invention has for itsobject to provide a gate of the character named with simpl'e meanswhereby the gate may be held trom movement when in either its closed oropen position.

Figure I is a top or plan view of my gate shown in closed position. Fig.II is a horizontal section taken on line II II, Fig. III. Fig. III is anelevation of the gate in open position. Fig. IV is a verticalcross-section taken on line IV IV, Fig. I.

A designates a portion of the end wall of a car to which my gate isattached.

1 designates hinge-brackets that are secured to the car end wall toserve as supports for the gate. The gate proper consists of aborder-band 2, in which are seated rods 3. The border-band has securedto it hinge-lugs 4, which are pivotally connected to thehingebrackets 1in a manner to provide for i'ree swinging motion of the ate.

5 is an end lrod mem er that is secured to the upper portionofthe-border-strap 2 by arms provided in connection therewith and isalso secured to the rear vertical portion of the border-strap by stems6. The said end rod member is thereby provided with both a horizontalportion and a vertical portion, which may be conveniently grasped by apassenger in entering or leaving the carplatform when the gate is inopen position.

7 designates a slotted guide secured to the car end wall A in ahorizontal position, the said guide being made of channel form andhaving the slot therein of less width than the width of the channel. Atthe upper side of the guide 7 and adjacent to its end nearest the pointof hinged support of the gate is a housing 8. In this housing is aretainingbolt 9, that is provided with a head 10, preferably having arounded point, and adapted to project across the slot inthe guide 7.(See Figs. III and IV The shank of the retaining bolt is surrounded byan expansionspring 11, located within the housing 8, which serves tohold the head of the bolt projected romthe housing. The shank of saidbolt has secured to it at its upper end a handle 12, by which the boltmay be re- -tracted against the action of the spring 11.

13 designates a link that is loosely iitted to one of the gate-rods 3 toturn thereon, the end of the link connected to said rod being supportedby a tie-bar 14, that connects several of the rods 3. The end of thelink 13 opposite that fitted to a rod of the gate, as mentioned, isarranged to move in the uide 7, and on said end at its upper and owersides are studs 15, that are adapted to ride in the channel of theguide, where they serve as members to prevent the escape of the linkfrom said Guide. Projecting from the end of the link last mentioned is atooth 16, that is arranged to ride in the slot of the guide 7 from endto end thereof and is adapted to move into a position adjacent to thehead of the retaining-bolt 9 when the gate is in closed position, asseen in Figs. I and IV.

When in the practical use of my gate the gate is moved into closedposition, as seen in Fig. I, the link 13 is drawn with vthe gate untilits free end riding in the guide 7 is brought into juxtaposition withthe retaining-bolt head 10. As the free end of the link approaches theend of the guide at which the locking-bolt is located, the tooth 16 onthe link impinges against the retaining-bolt head and acts toreciprocate the retaining-bolt in its housing to permit said tooth topass the head of the bolt. The head of the bolt then returns to itsformer position and becomes seated against the forward face of the tooth16, where it serves by bearing against said tooth to prevent endwisemovement of the link 13 in a rearward direction, thereby holding thegate in its closed position. When the gate is to be swun into openposition, the lretaining-bolt is wit drawn from engagement with thetooth of the link 13 by grasping its handle 12 to withdraw the head ofthe bolt into the housing 8. The free end of the link may then ride inthe guide 7, while the gate is being moved into the open position shownin Figs. II and III, the movement being continued until said link lieslongitudinally within the guide. As the link is finaIlybrought into theposition within the guide it strikes against the head of the retainin-bolt, thereby moving said head into the ousing 8 to IOO IOS

permit the link to pass beneath it. Immediately after the link haspassed beneath the head of the bolt said head is thrown out- Ward ly ordownwardlyT into a position infront of the link to engage it andsecurely hold it from movement, and the gate is thus held in openposition.

I claim as my inventionl. The combination with a swinging gate, of aguide, a link connected to said gate and arranged to operate in saidguide, and a retaining-bolt supported by said guide and arranged toengage said link, substantially as set forth.

2. The Combination with a swinging gate, of a link connected to saidgate, a guide in which said link operates and a spring retaining-boltCarried by said guide, substantially as set forth.

3. The Combination With a swinging gate, of a guide, of a link connectedto said gate and provided with a tooth, and a retainingbolt arranged toengage said tooth g said link being arranged to operate in said guide,substantially as set forth.

""'"`4. The combination with a swinging gate,

of a Channel-guide, a link pivoted to said gate and provided with studsarranged to operate in the Channel in said guide, and a retaining-boltarranged to engage said link to hold it from movement in said guide;said link being provided with a tooth to be engaged by saidretaining-bolt, substantially as set forth.
